Late fees are an unnecessary expense, and "I forgot" is the most expensive reason to pay them. FluidGrids turns a simple bill-tracking sheet into a self-running reminder system.
Keep a Google Sheet with bill name, amount, due date, and a notes column. Drop a schedule trigger that fires every morning at 8 AM. A Google Sheets node reads the full list, an If node checks whether each bill is due in the next 3 days and has not been paid yet, and a SendGrid node emails you a tidy reminder with the bill name, amount, and due date.
The trigger is real and the check is data-driven — add a bill to the sheet and it gets included in the next morning's run; mark it paid in the sheet and the next reminder skips it. There is no separate system to maintain.
Add a Switch node to handle multiple reminder tiers — a soft reminder 3 days out, a firm reminder the day before, a final note the day-of — without rewriting the workflow. Add a Slack node to also ping a partner's channel for shared bills, or add a Google Sheets row marking the bill as "reminded" so each bill only fires once per cycle.
Because each bill is its own run, the per-node observability FluidGrids is built for applies directly — open any past run to see which bills were checked, which were filtered out, and which reminder was sent. No more guessing whether the system noticed a bill or not.
It is the smallest possible automation for the most common personal finance chore: bills tracked, reminders sent, late fees gone.
Do it yourself
Read upcoming bills from a Google Sheet on a schedule, filter for bills due in 3 days, and email a friendly reminder to yourself.
Maintain a Google Sheet with bill name, amount, due date, and a paid status column.
You should see: The sheet becomes the single source of truth for upcoming bills.
